The 42-year-old Hollywood actress travelled with her children to the African country of Namibia earlier this month for a special cause: to open the Shiloh Wildlife Sanctuary.

The sanctuary cares for elephants and rhinos that have fallen victim to poaching and abuse, and it's the latest project from the N/a’an ku sê Foundation.

The cause is close to 11-year-old Shiloh, who was born in Namibia.

"Her face lit up when she saw the sanctuary for the first time,” a source told People. "The name was a surprise to her and she was beaming. She and her brothers and sisters moved around very quietly as the newly rescued elephants were still settling in."

During their five-day stay, Angelina met with N/a’an ku sê founders Rudie and Marlice van Vuuren to discuss the Sanctuary and other projects of national conservation interest.

The Maleficent star and the kids spent five days there, where they got hands-on experience working with the wild animals.

Animals that come to the facility will be cared for until they are fit and ready to be returned.

Upon returning home to the States, it wasn't long before the family was off again -- to California's Disneyland -- to celebrate twins Knox and Vivienne's 9th birthday.

The actress brought along the rest of her and Brad Pitt's clan — Maddox, 15, Pax, 13, Zahara, 12, and Shiloh, 11 — for the festivities, too.

"They have a guide and bodyguards, but people aren’t bothering them,” an onlooker told Us Weekly.
